What You Will Need
- A motorcycle lift or stand
- A wrench or socket set
- A clean container to catch brake fluid
Step 1: Elevate the Motorcycle
Place your motorcycle on a lift or stand to elevate the wheels off the ground. This allows for better access to the brake calipers and bleeder valves.
Step 2: Locate the Brake Bleeder Valve
Refer to your motorcycle’s manual to find the location of the brake bleeder valve. Typically, it is found on the brake caliper or wheel cylinder.
Step 3: Prepare the Brake Bleeding Kit
Attach the clear plastic tubing from the brake bleeding kit to the bleeder valve. Place the other end of the tubing into the clean container to catch the old brake fluid.
Step 4: Top up Brake Fluid Reservoir
Check the brake fluid reservoir, usually located on the handlebars or near the engine. Ensure the reservoir is filled with new brake fluid to avoid introducing air into the system during the bleeding process.
Step 5: Open the Bleeder Valve
Using a wrench or socket set, gently loosen the bleeder valve. Make sure the tubing is securely attached.
Step 6: Pump the Brake Lever
Sit on your motorcycle and slowly pump the brake lever several times. This will force the old brake fluid and any trapped air out through the tubing. Keep an eye on the fluid level in the reservoir, topping it up as necessary.
Step 7: Close the Bleeder Valve
Once you observe clear, bubble-free brake fluid flowing through the tubing, close the bleeder valve tightly. Remove the tubing from the valve.
Step 8: Double-Check and Repeat
Check the fluid level in the reservoir and ensure it is at the proper level. If necessary, repeat the bleeding process for each caliper, starting with step 3.
Step 9: Test Your Brakes
With the bleeding process complete, carefully lower your motorcycle and start the engine. Test the brakes by gently squeezing the brake lever. It should feel firm and responsive. If not, consider rechecking the bleeding process or consulting a professional mechanic.
Step 10: Dispose of Old Fluid Responsibly
Brake fluid is hazardous and should not be disposed of improperly. Ensure you follow local regulations for safe disposal of the old brake fluid.
Performing a motorcycle brake bleeding is an important maintenance task that improves your bike’s braking performance and overall safety. By following this step-by-step guide, you can confidently bleed your motorcycle’s brakes and enjoy a smooth and reliable riding experience.
